It was fine until the third time i sprayed it. it was a 30 dry shot to cool down the boost from the supercharger but now i go a ticking thats pretty loud ive adjusted the valves three times now and the noise is still there, its definitley top end, any input would be appreciated

 

Theres no loss of power at all like a messed up valve

 

if you got one of those valves really hot they can chip or warp. nitrous without enough fuel will warp an exhaust valve in short fashion. any chance this happened? did you dyno tune your nitrous setup with a wideband to make sure it wasn't going lean?

 

The spray tune up was a solid 12.3 to 12.5 on the wideband, i pulled 12 degrees of timing for 12 lbs of boost and the 30 shot, i figured that would be a safe

 

with that much timing out all sorts of **** could be safe. i would look at the plugs and see what they have to say.

 

The plugs look fine. The heat line is rite in the bend on the plug. do you think im pulling to much timing? if so what should i go with.
